ubuntu 12.10 - No Wireless Dell d430/d830 with Broadcom BCM4311

[daz23]

Again, Broadcom BCM4311 wireless chipset is not being detected correctly on Dell Latitude D420/D820 and higher series. This is going on 2 years or more now.

You have to run the following commands from terminal, to get the wireless to work on a Dell d420/d430 or Dell d820/d830. Don't forget to reboot.

sudo apt-get remove bcmwl-kernel-source
sudo apt-get install firmware-b43-installer b43-fwcutter

Just to confirm that this fix is also correct for the Acer Aspire 7520, also with Broadcom BCM4311.

Wifi setup is very much better now, 12.04 was an absolute nightmare, now the only fix still needed is making the driver selection process (jockey?) pick the correct drivers for the 4311 automatically. It should not take the relevant developer much effort to fix it now. The problems with the network manager and other parts of the system, which have been problematic for at least two years, appear to have been completely fixed, and there is now no need to install wicd and do lots of other things to get wireless to work.

Many thanks to everyone who has been working on this.

After running 12.10 updates on my laptop with Broadcom 4312 wireless my wireless broke with the new 3.5.0-18 kernel update.
To fix I went into Software Sources & disabled the STA driver then I'm assuming at least the last 3 commands in this fixed it:

sudo modprobe -r b43 ssb wl
sudo apt-get remove bcmwl-kernel-source 
sudo apt-get install build-essential dkms linux-headers-generic
sudo apt-get install bcmwl-kernel-source

I didn't have to reboot or anything. It just immediately found my wireless adapter and connected wirelessly again.

I ran into this problem on a MacBook Pro 5,4 and had the same problem after a fresh install of 12.10. Jawz101, thanks for the solution!

jawz101 - thank you! This worked for me (MacBook Pro 5,5 after an update to kernel 3.5.0-18)

This solution worked for me... Dell Latitude D630. Muchas Gracias!

jawz101, the solution you posted worked perfectly on a Lenovo 3000 N500 with Quantal 64 bit, when the wireless went dead after updating to kernel 3.5.0-23

Thanks pal!

Neither of these worked on my Acer aspire one 722. I couldn't get internet to finish the first one though, even my Ethernet doesn't work
